how much mhz

[schmuckpussy]

How much mhz is sufficient these days. Should i just buy the maximum (about 400mhz i think) or is there no difference when i buy less.

What does PC3300 mean and what is the difference between PC... and ...mhz

I hope anyone can help me out of this. My Mobo is a P4P800 deluxe and only supports ddr

It's the beat that will not be denied

Hehe, OK, PC3200 is DDR400 and runs on a 200MHz bus clock. Your board supports Dual Channel which doubles memory bandwidth so that DDR400 matches Intel's QDR800 CPU bus.

3200 means 3200MB/s. It works like this:
200MHz, x2 because it's DDR (that's why they call it DDR400, or lie and call it 400MHz RAM).
It's on a 64-bit bus
There are 8 bits to a byte, so divide 64 by 8 and get 8
Multiply 400x8, you get 3200MB/s.

How much mhz should i buy. I think i'll go for 1 module of 512mb, but how much mhz should it have. Should i buy the ddr400 (maximum these days i think) or is that a waste of my money

I hope you can help me out with this

Since you go for P4P800 board, you should aim for two sticks of DDR400 to match it.

Actually DDR400 (PC3200) is specified for your chip at stock speed. If you use slower memory, the RAM will run slower than the CPU bus creating a performance bottleneck, as well as creating overhead in the memory controller.

There are faster versions of PC3200 for overclockers, which are PC3500 (DDR433), PC3700 (DDR466), PC4000 (DDR500), and even PC4200 (DDR 533).

If you're not overclocking PC3200 is perfect.

Not to be a smartass, but if you are asking those sorts of questions, you should probably stick with 2 sticks of 256M--unless money is no object.

I have the Corsair TwinX PC4000-Pro 1024MB kit in mine. I got it because I couldn't afford anything else.
